LINOTYPE-MACHINE.

Specification of Letters Patent.

Patented. Sept. 26, 1905.

Application filed May 19, 1905. Serial No. 261,171.

To (LZZ whom, it may concern:

' discharging the matrices.

It consists in an improved manner of sustaining and adjusting themagazines, in the manner of supporting and adjusting the cooperatingescapement mechanism, and in improved details of the escapement devices.

IVith the exception of the parts herein shown and described the machinemay be of any ordinary or suitable construction.

Referring to the drawings, Figure 1 is a side elevation of the magazine,the upper portion of the main frame, and the cooperating parts. Figs. 9.and 3 are longitudinal vertical sections through the forward end of thesame. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is aperspective view of one of the escapements.

Referring to the drawings, A represents a main frame, which may be ofany form adapted to sustain the operative parts.

B is an inclined base-frame for the magazine, mounted at its upper endon a horizontal rod or pivot O, seated in the top of the main frame, thearrangement being such as to permit the frame B to swing upward anddownward at its lower end. At its lower end the frame B is supported onone or more adjusting-screws D, seated in the main frame. I prefer toemploy two non-rotating screws passing through nuts (Z, seated in themain frame and each operated by a pinion cl on a horizontal shaft (Zseated in the main frame and provided with a hand-wheel 623. This shaftmay be extended, as shown, through a transverse slot in the screw,whereby the rotation of the screw is prevented. The turning of thehand-wheel serves to rotate the nut, and thereby raise or lower the endof the frame B. p v

The magazine consists of a series of sections E E, &c., lying one uponanother, the

whole series removably seated upon the underlying frame B. To keep themagazines in position and permit their convenient removal, the frame Bis provided on each side with an upright cheek plate 6' to bear againstthe lower ends of the projections e on the edges of the magazines. Withthis arrangement the magazines, which will be laid loosely together,tend to slide downward in an endwise direction,and the projections 0,bearing against the plates I), will hold their lower ends in line and inproper operative relations.

The frame B serves, it will be seen, not only to support the multiplemagazine, but also to raise and lower it, so that the lower end ofeither section may be brought in operative relation to the escapementdevices.

The magazines are grooved or channeled internally to receive and guidethe upper and lower edges of the matrices F, as in the ordinaryMergenthaler linotype-machine.

The escapement mechanism consists of a series of upright slides H, equalin number to the channels in one magazine." These slides are mounted tomove upward and downward side by side in a supporting-bar I, whichextends horizontally across the lower end of the magazine, its endsbeing sustained by trunnions 2' in the upper end of a vibrating frame K,sustained at its lower end by pivots Lin the main frame. Theescapement-slides H have their upper edges exposed directly against thelower end of the magazine. In order to keep the bar I and the containedslides in operative relation to the magazine, a spring M is extendedfrom the rocking frame K to the magazine-frame, as shown in Fig. 1, itseffect being to maintain close connection between the bar I and the endof the magazine, while at the same time permitting the bar to rock ortilt slightly that it may adjust itself to the varying angle orinclination which the end of the magazine assumes as it is swung upwardand downward. Each of the slides H is formed in its side face with atransverse groove or channel it, forming a continuation of the adjacentchannel in the magazine, so that when the slide is lowered to theposition shown in Fig. 3 the foremost matrix may advance from themagazine into the slide the width of which is equal to the length of thematrix.

The escapement-supporting bar I, commonly known as the escapement-bar,is

formed at the front with openings through which the matrices may passfrom the escapement-slides. The bar is formed, as shown, with shouldersa", standing at such height that when the matrices enter from themagazine their forward ends abut against the shoulders, by which theirfurther advance is prevented. The discharge of a matrix is effected bylifting the slide from its receiving position, Fig. 3, to the positionshown in Fig. 2, the effect being to lift the contained matrix above theshoulder 6, over which it passes endwise.

During the rise of the matrix to the discharging level its upper or rearend bears against and holds back the next matrix in the magazine untilit is engaged, as shown in Fig. 2, by the eseapement-slide, whichprevents its advance when the first matrix is released. When the slidefalls to its original position, the next matrix in turn advances fromthe magazine into the escapement-slide and is arrested by the shoulderd.

It will be seen that in the normal position of the parts the matricesare contained Wholly within the magazine and that the escapement devicesare empty. The advantage of this construction lies in the fact that theend of the magazine may be moved upward and downward at any time inorder to bring the required section into action, and this withoutreturning or restoring to the magazine matrices which have passedtherefrom into the escapement devices. In all escapementmechanismsheretofore employed in connection with a movable magazine one or morematrices have been retained at all times in the escapement mechanism andthe magazine cannot be moved until the matrices have been restoredthereto, an operation involving both considerable time and effort.

The eseapement may be modified in form and arrangement, provided itretains essentially the mode of action above describedthat is to say,provided it is adapted to 006perate with the magazine and normally holdwithin the same all matrices which have not been permitted to pass tothe line.

The slides H may be supported and actuated in any suitable manner. Iprefer to effect their depression by springs M, secured to theescapement-bar I and bearing on the upper ends of the respective slides,as shown.

In order to maintain the slides in their normal elevated positions,(shown in Fig. 2,) I have provided angular levers 0, having midway theirlength lips 0, which are seated in bearings formed in the bar I. Theselevers are adapted to bear at their rear ends upward against the underends of the escapement-slides H, while their forward ends are adapted tobe engaged by the vertically-sliding reeds or bars P, connecting withthe finger-keys and acted upon by springs S of strength sufficient toovercome the springs M.

It will be observed that the levers O are adapted to be slipped intotheir places and to be removed therefrom at will. They are advantageous,in that they avoid the necessity for pivot-pins, each lever being freefor removal or insertion independently of the others.

I believe myself to be the first to combine with an inclined magazinewherein the matrices slide on edge an escapement device constructed toact when in one position as a continuation of the magazine-channel toreceive and support a single matrix, bearing at its end against a fixedstop, and also serving when moved to another position to lift thecontained matrix clear of the detaining-shoulder and at the same timehold back the next succeeding matrix. The details may be varied,provided this mode of action is retained.

The matrices discharged from the escapement devices are received in theverticallychanneled front or guide I through which they descend to theusual devices by which they will be assembled in line, as in theordinary linotype-machine. The matrices may be held back in thosemagazine-sections which are not in use by any suitable meansfor example,by bars R thrust transversely through slots in the magazines in positionto engage belowthe upper ears of the matrices-or the escapement bar orframe I may be extended upward, as shown at 21* in Fig. 2, to cover theends of the magazine-sections.
